Circuit breakers are a important safety feature in any wiring system, as they interrupt electrical flow in the event of an overload, overload, or short circuit. The LELPK11-1REC4-35504-1-V, commonly referred to as a molded case or dry type circuit breaker, is designed to meet the stringent safety needs of commercial and industrial applications. This article will discuss the application fields and working principles of this particular breaker.

Application Fields

The LELPK11-1REC4-35504-1-V molded case circuit breaker is rated up to 600 amps at 480 volts, making it suitable for both residential and commercial applications. It is commonly used in large commercial and industrial buildings to provide overcurrent protection in multi-wire branch circuits. It can also be used to protect high current machinery or heavy appliances in industrial plants.

This breaker is also popular in hospitals, as it meets the stringent safety requirements for health care facilities. It is designed with a current limiting feature, which helps protect sensitive equipment from electrical faults or overloads. This feature is also important for use in hazardous locations, as it reduces arcing to a minimum.

Working Principle

The working principle of the LELPK11-1REC4-35504-1-V circuit breaker is based upon a thermal-magnetic tripping system. This system consists of two separate overcurrent protection systems. The first is a thermal component which is designed to detect an overload and trip the circuit if the current exceeds the breaker\'s rating. The second is a magnetic component, which will sense a short circuit and open the circuit before damage can occur.

These two components work together to provide maximum protection against electrical faults. The thermal component has a small bimetallic strip that heats up in response to an overload. When the strip reaches its predetermined temperature, it trips the circuit to prevent unnecessary damage. The magnetic component consists of an electromagnet which is energized in the presence of a short circuit. When the magnetic field builds up to a certain level, the circuit is opened.

The LELPK11-1REC4-35504-1-V also features several other important safety features, such as a no-volt release button which locks the breaker in the off position, preventing it from being accidentally switched on. It also has a warning indicator which warns the user if the breaker has been tripped and needs to be replaced. Finally, it has an insulated casing which provides a level of protection against accidental contact with live parts.

In summary, the LELPK11-1REC4-35504-1-V is a highly reliable and versatile molded case circuit breaker that is suitable for use in a variety of commercial and industrial applications. Its thermal-magnetic tripping system provides effective protection against overloads and short circuits, while its additional safety features make it an ideal choice for use in hospitals and hazardous locations. This breaker helps ensure a safe environment for employees, clients, patients, and equipment.
